Question

Amanda plans to have 20 friends over to Watch NCAA Basketball on Saturday. She plans to serve pizza, wings, soda, and brownies. Each person eats 3 pieces of pizza, 16 ounces of soda, and 1 brownie. Each pizza has 10 slices. She buys 64 oz. bottles of soda. She bakes brownies in 8” X 12” pan and cuts them into 2” X 3” pieces.

How many pizzas does she need?
How many soda bottles does she need?
How many pans of brownies does she need?

If bottles of soda cost $1.69, pizzas cost $12.99, and brownie mix cost $2.39, write an expression to calculate the cost of Amanda’s NCAA tournament party.

Answer 1

In total, she will need $98.34 to pay all of the foods she plans to serve at the party.

All of the work:

How to solve the amount of pizza she needs:

20 x 3 = 60

60 divided by 10 = 6

How to solve the amount of soda bottled needed:

20 x 16 = 320

320 divided by 64 = 5

How to solve the number of pans she needs:

20(2 x 3) = 40 x 60

40 x 60 divided by 8 x 12 = 5

THE COST CAN BE FOUND BY MULTIPLYING THE NUMBER OF THE ITEM NEEDED AND THE PRICE FOR EACH OF THE ITEM.

Number of pizza she needs:6 pizza, costs $77.94

Number of soda bottles she needs:5 bottles, costs $8.45

Number of pans she needs:5 pans, costs $11.95

Add 77.94, 8.45, and 11.95 and get 98.34
